This panel displays on the right side when you click a user's (or other directory object's) name in the Search Results Panel on the left side.
The Details panel has two tabs: Information and Organizational Chart (unless the eGuide administrator has disabled the Org Chart feature). The Information page shows general information about the user and might display the user's photo. The Organizational Chart page shows the user, the user's manager, and all the other users who report to that manager.
